I know there are other threads on this, but none seem current. I am not even able to open the internet mail settings and there is no option to default my Google calendar, even though it is registered with the device. I registered the device again and I was at least able to get to the internet or enterprise options but nothing goes past there. Ever since I updated my phone (which bricked it initially Version 7.1 build 1737) my phone has been working like crap. Slow/unresponsive touch screen and now this. Any suggestions?
